Adductor canal block (ACB) has recently emerged as an alternative to femoral nerve block for pain control after various knee procedures especially knee arthroplasty. In this review article, we will review the anatomy of adductor canal, sonoanatomy, and ultrasound-guided approach for ACB as well as review current evidence regarding the indications of the ACB.

The benefits of high-quality postoperative analgesia are well documented and include earlier mobilization, fewer respiratory and cardiovascular complications, and shorter hospital stay. Local anesthesia-based acute pain regimens are at worst equal to and at best superior to opiate-based regimens from the perspective of analgesia. ⋯ There is an identified need for further methods to optimize longer-acting delivery of these agents. This article reviews current and evolving longer-acting techniques and their limitations with particular focus on the potential advantages of a fibrin hydrogel-based system.

To assess the ability of field tests of exercise tolerance, such as the 6-minute walk test (6MWT) and incremental shuttle walk test (ISWT), to predict postoperative outcome following intra-abdominal surgery. ⋯ Field tests may be able to predict postoperative outcome; however, further validation is needed. The ISWT appears to be the superior field test. The 6MWT and stair climb test require further validation to assess their predictive ability.

Peripheral nerve blocks in the management of postoperative pain: challenges and opportunities.
Peripheral nerve blocks (PNBs) are increasingly used as a component of multimodal analgesia and may be administered as a single injection (sPNB) or continuous infusion via a perineural catheter (cPNB). We undertook a qualitative review focusing on sPNB and cPNB with regard to benefits, risks, and opportunities for optimizing patient care. Meta-analyses of randomized controlled trials have shown superior pain control and reductions in opioid consumption in patients receiving PNB compared with those receiving intravenous opioids in a variety of upper and lower extremity surgical procedures. cPNB has also been associated with a reduction in time to discharge readiness compared with sPNB. ⋯ Potential infectious complications of catheters, although rare, include local inflammation and infection. Other considerations for ambulatory cPNB include appropriate patient selection, education, and need for 24/7 availability of a health care provider to address any complications. The ideal PNB technique would have a duration of action that is sufficiently long to address the most intense period of postsurgical pain; should be associated with minimal risk of infection, neurologic complications, bleeding, and local anesthetic systemic toxicity; and should be easy to perform, convenient for patients, and easy to manage in the postoperative period.
